C problem

Hey, what is the function to clear the command window in C from everything thats been printed in it?

Thanks for the help,

You can use the non-ANSI standard function clrscr(), but it would be better to make one yourself. Or, if you'd rather, here's a function I modified from someone else to do the same. You'd pass it the handle to the console output (ie. HANDLE console_out_h = GetStdHandle(STD_OUTPUT_HANDLE))

#include <windows.h>

int ClearScreen(HANDLE console_out)
{
DWORD writ, len;
CONSOLE_SCREEN_BUFFER_INFO console_buffer_info;
COORD start = {0, 0};

GetConsoleScreenBufferInfo(console_out, &console_buffer_info);
FillConsoleOutputCharacter(console_out, (TCHAR)32,
(console_buffer_info.dwSize.X * console_buffer_info.dwSize.Y), start,
&writ);

GetConsoleScreenBufferInfo(console_out, &console_buffer_info);
FillConsoleOutputAttribute(console_out, console_buffer_info.wAttributes,
(console_buffer_info.dwSize.X * console_buffer_info.dwSize.Y), start,
&writ);

SetConsoleCursorPosition(console_out, start);

return 0;
}

Something like that is probably the best way *if* you're using windows.

If you compiler has it..

#include <conio.h>

int main()
{
clrscr();

return 0;
}



A quick way I sometimes use is the system() command..

#include <stdlib.h>

int main()
{
system("cls"); // windows

system("clear"); // gnuc

return 0;
}

Thanks alot for the help... Thats exactly what I needed
